专利号:WO-2020181929-A1 优先权日:2019-03-08 标题 :Preparation method for heptamethylbenzylindole cyanine dye and application thereof 发明人:WU AIGUO; LI JUAN; JIANG ZHENQI; YUAN BO 权利人:CIXI INSTITUTE OF BIOMEDICAL ENGINEERING NINGBO INSTITUTE OF INDUSTRIAL TECH CHINESE ACADEMY OF SCIE; NINGBO INSTITUTE OF MATERIALS TECH & ENGINEERING CHINESE ACADEMY OF SCIENCES 摘要:The present application relates to the fields of polymethylbenzylindole cyanine dyes and the preparation thereof, and disclosed thereby are a preparation method for a heptamethylbenzylindole cyanine dye and an application thereof. The method comprises the following steps: 1) reacting raw materials comprising a 2,3,3-trimethyl-4,5-benzoindole derivative and a nucleophilic substitution compound under vacuum conditions at an increased temperature to obtain an organic ammonium salt; 2) reacting the organic ammonium salt obtained in step 1) with a solution of a cycloolefin derivative at an increased temperature under closed conditions. The structural formula of the heptamethylbenzindole cyanine dye is as shown in formula (I). The dye has near-infrared light absorption and fluorographic properties, and can be used as a probe auxiliary. The method has the advantages of having a short synthesis route, having a friendly solvent environment, having a simple process, preventing noble metal catalysis, having high yield, having high purity, and so on, has high applicability, and can be used to synthesize products of various structure types.
